When learning about Benito Juarez most people focus on the separation of church and state and on the defeat of the Second Empire, but I want to know what measures he took specifically to help the indigenous people.

For 300 years indigenous people had been legally discriminated, and after that was abolished, natives like Juarez were able to climb through the ranks, but ending the legal discrimination wasn't enough to counteract 300 years of racism, right?, new measures had to be taken to undo those centuries of damage, what were those measures?, how successful they were?
